There are 228 other poultry farms in the 10 kilometer zone. Due to the contamination and the high poultry density, a transport ban applies in the region. This transport ban, which partly lies in the province of Utrecht, runs from Utrecht to the east and includes Baarn, Amersfoort, Zeist and Wijk bij Duurstede. This concerns a transport ban on all birds, hatching and table eggs from a location with photos. In addition, there are still national measures in place, such as a ban on visiting bird roosts of risk birds, unless it is necessary. Birds at risk include gallinaceous birds (such as chickens), waterfowl and ratites.
